Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] As Figures 1 to 9 shown, a steel structure workshop hoisting construction device according to the present invention includes a suspension seat 1, a lifting tool 2 and a steel wire rope 3; a pair of the lifting tool 2 and the steel wire rope 3 are provided. A pair of driving mechanisms 4 are fixedly connected to the surface of the suspension seat 1; a pair of winches 5 are rotatably connected to the bottom of the suspension seat 1, and the winches 5 are respectively controlled by the driving mechanisms 4 to rotate; a pair of the steel wire ropes 3 are respectively connected between the winches 5 and the lifting tool 2. A pair of mounting blocks 6 are fixedly connected to the side surface of the lifting tool 2; a guide post 7 is fixedly connected between the mounting blocks 6; a pair of fork walls 8 are slidably connected to the surface of the guide post 7.

[0025] In the prior art, a two-point hoisting method is usually adopted for steel members. However, in actual operation, it is difficult to accurately determine the hoisting points. Especially for some members with variable cross-sections, such as large-span beams, trusses, cantilever beams, etc., their cross-sectional shapes or dimensions change continuously along the length direction, and it is difficult to judge the center of gravity position of the members. Therefore, it is impossible to quickly determine the specific hoisting parts of the members during hoisting, resulting in the inclination and shaking of the members after being lifted, and there are potential construction safety hazards.

[0026] When the present invention is in use, the two lifting tools 2 are placed at both ends of the steel member, a pair of fork walls 8 of the lifting tool 2 are inserted into the grooves of the member, and the mounting blocks 6 are abutted against the end faces of the member. Then, the suspension seat 1 is lifted by a hoisting device, so that the steel member rises slightly a small distance and leaves the ground. At this time, the steel member is in a suspended state. If it is inclined, the winch 5 at the lower end of the member is controlled by the driving mechanism 4 to rotate, and the steel wire rope 3 on this side is wound up a certain length (or the steel wire rope 3 on the other side is released) until the member reaches a horizontal state. After that, normal hoisting operations can be carried out, which can improve the stability of the member after being suspended, reduce the phenomena of shaking and slipping, and improve the construction safety and efficiency.

[0027] A guide rod 9 is fixedly connected to the bottom of the sling 2; a pair of movable rings 10 are slidably connected to the surface of the guide rod 9; support ribs 11 are fixedly connected between the movable rings 10 and the fork walls 8 respectively. By providing the guide rod 9, the movable rings 10 and the support ribs 11, the support strength of the fork walls 8 for the steel members can be enhanced, and the hoisting stability can be further improved.

[0028] As another embodiment of the present invention, an inclined cylinder 12 is fixedly connected to the top of the sling 2; a piston 13 is slidably connected inside the inclined cylinder 12; a telescopic column 14 is fixedly connected to the upper side of the piston 13; a buffer spring 15 is fixedly connected between the piston 13 and the inclined cylinder 12; one end of the telescopic column 14 extending outside the inclined cylinder 12 is connected to the steel wire rope 3. When hoisting, the steel wire rope 3 can drive the telescopic column 14 to move outside the inclined cylinder 12 and compress the buffer spring 15, and the buffer spring 15 is used to buffer and relieve the tensile stress at the moment of hoisting, playing a role in protecting the steel wire rope 3, preventing the problem of fatigue and fracture of the steel wire rope 3 due to excessive tension caused by the overweight of the steel member, being applicable to large factory building members, and extending the service life of the device.

[0029] As another embodiment of the present invention, reset springs 16 are fixedly connected between the fork walls 8 and the mounting blocks 6 respectively; a connecting plate 17 is fixedly connected to the top of the telescopic column 14; a tensioning rope 18 is fixedly connected between the side of the fork wall 8 far from the mounting block 6 and the connecting plate 17; pulleys 19 are arranged at the turning points of the tensioning rope 18. When the telescopic column 14 extends upward, it can drive a pair of tensioning ropes 18 to move upward synchronously through the connecting plate 17. Then, the lower ends of the tensioning ropes 18 drive the fork walls 8 to slide horizontally on the surface of the guide posts 7, so as to prompt the pair of fork walls 8 to approach each other and clamp the middle part of the steel member, locking and fixing the sling 2 and the member, and preventing accidental separation between the sling 2 and the member during hoisting.

[0030] It should be noted that this embodiment is only applicable to members with a middle beam in the cross-sectional shape such as H-shaped steel and I-shaped steel.

[0031] As another embodiment of the present invention, a group of anti-slip convex points 20 are evenly distributed on the upper side surface of the fork walls 8, and the anti-slip convex points 20 have a certain elasticity. After the fork walls 8 are attached to the steel members, the anti-slip convex points 20 can be used to increase the friction damping between the two, thereby preventing accidental sliding between the fork walls 8 and the members during hoisting and causing the members to slip, and further improving the safety factor.

[0032] As another embodiment of the present invention, the connection between the piston 13 and the inclined cylinder 12 is a sliding seal connection; an air groove 21 is opened inside the fork wall 8; a hose 22 is communicated between the air groove 21 and the bottom of the inclined cylinder 12; a group of guide holes 23 are evenly distributed between the upper side of the fork wall 8 and the air groove 21.

[0033] When the telescopic column 14 drives the piston 13 to move upward inside the inclined cylinder 12, a negative pressure is generated at the bottom inside the inclined cylinder 12, and air is sucked into the bottom inside the inclined cylinder 12. After the steel member is hoisted to the designated position, the steel wire rope 3 is relaxed. At this time, the buffer spring 15 drives the telescopic column 14 and the piston 13 to reset downward inside the inclined cylinder 12, so as to compress the air inside the bottom of the inclined cylinder 12 and squeeze it into the air groove 21 of the fork wall 8 through the hose 22, and finally spray it upward through a plurality of guide holes 23. Since the surface of the steel member may have substances such as dust, mud, rust, and scale due to its own reasons or construction site reasons, etc., these substances are likely to remain on the surface of the fork wall 8 after the fork wall 8 contacts the steel member. At this time, jetting air through the guide holes 23 can blow off the residues on the surface of the fork wall 8 and keep the upper surface thereof clean, thereby preventing the residual substances from reducing the contact effect and anti-slip effect between the fork wall 8 and the member.

[0034] A group of bent holes 24 are formed inside the anti-slip bump 20, and the outer end of the bent hole 24 is inclined downward; the bent hole 24 is communicated with the guide hole 23. When some of the guide holes 23 jet air, the air flow can spray out along the bent holes 24 inside the anti-slip bump 20, and since the outer end of the bent hole 24 is inclined downward, it can guide the air flow. Therefore, when the air flow sprays out, it can directly impact between adjacent anti-slip bumps 20 and the surface of the fork wall 8, thereby improving the wiping effect on the fork wall 8 and increasing the acting area of the air flow.

[0035] An air inlet 25 is communicated with the bottom of the inclined cylinder 12; one-way valves are arranged inside both the air inlet 25 and the hose 22. By providing the air inlet 25 and the one-way valve, when the piston 13 moves downward, the one-way valve of the air inlet 25 is in a closed state, and the one-way valve of the hose 22 is in a conducting state. Therefore, the air inside the bottom of the inclined cylinder 12 is discharged through the hose 22 to clean the surface of the fork wall 8. When the piston 13 moves upward, the one-way valve of the air inlet 25 is in a conducting state, and the one-way valve of the hose 22 is in a closed state. Therefore, the external air can be re-sucked into the bottom inside the inclined cylinder 12 through the air inlet 25, and such a working cycle is formed, so that the guide holes 23 only play the role of discharging air, avoiding the problem that impurities on the surface of the fork wall 8 are sucked into the air path structure during inhalation and causing blockage.

[0036] As another embodiment of the present invention, chutes 26 are formed at the corresponding positions of the bottom of the suspension seat 1 with respect to the steel wire rope 3; sliders 27 are slidably connected inside the chutes 26; compression springs 28 are fixedly connected between the sliders 27 and the chutes 26; the bottom of the sliders 27 is rotatably connected with coating rollers 29; The suspension base 1 is internally provided with a cavity 30 for storing a curing liquid, which is preferably a permeable lubricant with good fluidity, synthetic grease, petroleum-based grease, etc.; a transmission strip 31 is arranged inside the cavity 30; the other end of the transmission strip 31 is fixedly connected to the inside of the slider 27, and the end of the transmission strip 31 is in contact with the coating roller 29; both the coating roller 29 and the transmission strip 31 are made of water-absorbing materials.

[0037] When the pair of wire ropes 3 are in an open and taut state during operation, the wire ropes 3 can contact the coating roller 29. As the opening angle is different, the slider 27 and the coating roller 29 can be automatically adjusted up and down in cooperation with the compression spring 28. The transmission strip 31 can continuously conduct the curing liquid inside the cavity 30 to the inside of the coating roller 29 by means of capillary penetration. Then, when the winch 5 drives the wire ropes 3 to move, the coating roller 29 can roll on the surface of the wire ropes 3 and apply the curing liquid to the surface of the wire ropes 3. The curing liquid gradually flows downward along the top of the wire ropes 3, so as to realize the function of automatically applying the curing liquid to the wire ropes 3, form a protective film layer on their surfaces, reduce wear, corrosion, rust, fatigue and other phenomena during use, extend the service life of the wire ropes 3, and eliminate the need for manual regular application.

[0038] As another embodiment of the present invention, a separation cup 32 is fixedly connected to the bottom of the wire rope 3; a storage block 33 is arranged inside the separation cup 32; the storage block 33 is made of water-absorbing material. When the curing liquid on the surface of the wire rope 3 flows downward to the bottom of the wire rope 3, it will be blocked by the separation cup 32, so as to store the excess curing liquid inside the separation cup 32, prevent the curing liquid from flowing onto the lifting tool 2 and causing slippage between it and the component. By arranging the storage block 33 to adsorb and fix the curing liquid collected inside the separation cup 32, it can prevent the curing liquid from splashing out of the separation cup 32 under the action of shaking. When the storage block 33 is full, the separation cup 32 can be inverted regularly, and the storage block 33 can be squeezed from the opening of the separation cup 32 to squeeze out the curing liquid.

Taking the observer's perspective as the standard, the side of the device facing the observer is defined as the front, and the left side of the observer is defined as the left, and so on.
